The Gardiola landslide is a complex slide activated on 14-16 October 2000 located in the central part of the Germanasca Valley, in Salza di Pinerolo municipality (TO, Piedmont – northern Italy). This landslide consists of several sector with different kinematic: a portion reactivated during 2000, characterized by prevalent translational movement, and a low rotational component due to the foot erosion operated by the Germanasca torrent. A portion on the left side of this sector, that present a rotational component, was identified as the mainly active sector of the landslide during a survey in 2003. At the slope scale, the Gardiola landslide is included in a more extensive gravitative event, a quiescent event reported in the IFFI catalogue (IFFI project, Piedmont Region), extended from 1450 m to 1200 m asl. In the opposite side of the valley, in front of the landslide, was identified another quiescent landslide, extend from 1600 m asl to the bottom of the valley, at 1180 m asl. Starting from March 2004, a permanent topographic monitoring network has been installed on the landslide, with a robotic total station located on the opposite side of the valley. The landslide was monitored from March 2004 to April 2009.
